Schmidt named his 30-strong panel in Dublin this morning for the summer tour early next month.

Munster's Simon Zebo and James Cronin are in the 30-strong panel, however, along with Connacht scrum-half Kieran Marmion and Ulster pair Robbie Diack and Rob Herring.

Winger Zebo is back in after he was frozen out for the triumphant Six Nations campaign in the Spring.

Leinster pair Dave Kearney and Sean Cronin are out through injury and it's feared that Six Nations starter Kearney suffered a cruciate blow in Saturday's Pro 12 semi-final victory over Ulster.

Munster's Dave Foley is another to miss out after a strong season for the Reds.

"It's really just player management," said Schmidt. "There are guys who have had continuous niggly injuries that are going to be given a good bit of time in pre-season to recover.

"We believe they will be better served by having a window to rest."

Schmidt explained his reasoning for not taking either of the two Ians at out-half - Munster's Keatley and Leinster's Madigan - with Johnny Sexton and Paddy Jackson the no 10s touring.

"It's really that we believe to only take two scrum-halves would be really, really difficult," said the Kiwi.

"To go with six half-backs would be tight on numbers. I've had a really good discussion with Ian Madigan, he will go on the emerging tour with Ian Keatley.

"It's a chance to get game-time for them and we'll be keeping an eye on them over there.

"Johnny is in and has a spring in his step, and he's ready to go. That's a bonus for us."

Joe Schmidt in training with the Ireland squad

Brian O'Driscoll is retiring after the final on Saturday week and Ireland skipper Paul O'Connell admits Ireland have to move on without their world-class no 13.

"It's the start of a different era without him around the dressing-room, around the pitch," said O'Connell.

"But it's been coming for a while and a lot of players have been stepping up in that role over the last few years and in particular in the last few months.

"It's part of the cycle and you just have to get on with it."

And O'Connell is looking forward to the challenge against the Pumas.

"It's great, I've never toured there myself, it's a country I've never been to either," said the veteran second row.

"It's a fairly short tour, we're only there for three weeks. It's a tough challenge for us they're playing a lot more rugby than in the past so they'll be well prepared and it will be a tough, physical tour.

"One of the big thing Joe had at Leinster was competition for places and when you look at the names travelling to Argentina hopefully it will add to competition for Ireland."

Ireland will be leaving for Argentina the day after the Pro 12 final between Leinster and Glasgow at the RDS.

"There are 10 Leinster players coming on tour and we're just going to have to hope they're fully fit after the final," said Schmidt.

"That's why we have guys on stand-by, like Ian Madigan, Craig Gilroy and Tommy O'Donnell."
